Description
Technical field
The utility model relates to air-treatment technical field, be specifically related to evaporative pattern emission-control equipment, being mainly used in casting industry adopts lost foam process to produce on the equipment line of foundry goods, to pumped out by vavuum pump when producing cast, burnt by polystyrene foam plastics after produce, the process that reaches national requirements for environmental protection standard containing the multiple organic exhaust gas to person harmful substance.
Background technology
Lost foam casting because casting dimension accuracy is high, surface smoothness is good, the series of advantages such as technique wide accommodation, simple to operate, the labour intensity that greatly can improve foundry worker and environment is cast boundary and accepts and accreditation, be described as " green revolution of foundary industry ".Particularly during the last ten years, along with the development of auto industry, China's lost foam casting has had and has developed more rapidly, the manufacture of production line is also developed to the full automatic line closed by easy open file, single line casting output also increases gradually, can say that the Technology of EPC of China enters the technology maturation phase by the technological innovation phase.Can predict, in very long one period from now on, lost foam casting process will account for a stable market share in China's Foundry Production.
Need the tunica albuginea that burns, tunica albuginea and polystyrene foam plastics during lost foam casting cast, the waste gas containing benzene type organic generated after tunica albuginea burning enters in air by vavuum pump, causes pollution to surrounding environment.Before, the domestic environmental protection equipment not being specifically designed to the process of lost foam casting process gas.Applicant as the leading enterprise of domestic evaporative pattern device fabrication, be duty-bound ground using this device as research topic.
Detect through sampling, the harmful components contained by waste gas that during evaporative pattern cast, vavuum pump is discharged and concentration have exceeded national standard " discharge standard of air pollutants " (GB16297-2010) hazardous emission concentration and displacement requirements, must carry out innoxious process up to standard.
Applicant is through in many ways analyzing contrast to dilution diffusion method, flame combustion method, Production by Catalytic Combustion Process, water absorption method, absorption method, photocatalytic oxidation etc., final selected Production by Catalytic Combustion Process, think that the method know-why is advanced reliable, equipment investment and operating cost moderate, production management safe ready, process lost foam casting waste gas should be comparatively feasible.
Summary of the invention
The principle of lost foam casting emission-control equipment is by the waste gas containing organic pollution, first carries out preheating, after reaching uniform temperature, under the effect of catalyst platinum, palladium, the organic pollution in waste gas is oxidized to carbon dioxide and water, and releases heat.Reaction equation:
CmHnOx+O
2catalyst=CO2+H2O+Q
This reaction is a kind of typical gas-solid catalysis reaction, its essence is the treating technology effect that active oxygen participates in.Catalyst reduces active energy thus increases reaction speed, and catalyst also has certain adsorption effect, improves reaction rate.
Disclosed in this practicality, technical scheme is: evaporative pattern emission-control equipment, comprise steam-water separator, heat exchanger, preheating chamber, catalyst chamber, blower fan and valve, pipe fitting, it is characterized in that: described heat exchanger comprises the first air inlet, the second air inlet, the first gas outlet, the second gas outlet; Described steam-water separator import is connected with the vavuum pump exhaust outlet of combustion gas, and steam-water separator outlet is connected with air by by-passing valve on the one hand, enters valve be on the other hand connected with the first air inlet of heat exchanger by master; First gas outlet and preheating chamber and the catalyst chamber of connecting between the second air inlet of heat exchanger; The air inlet of the second gas outlet connecting fan of heat exchanger; Platinum, palladium catalyst is provided with in catalyst chamber.
Further, described master enters valve and also installs a fresh air valve communicated with air additional with heat exchanger.
Further, the second gas outlet of described heat exchanger also installs a cold-air door communicated with air additional with the air inlet of blower fan.
The utility model structure is simple, effectively the organic pollution in waste gas can be oxidized to carbon dioxide and water, reduces environmental pollution, meets environmental protection concept.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
A kind of evaporative pattern emission-control equipment, comprise steam-water separator, heat exchanger, preheating chamber, catalyst chamber, blower fan and valve, pipe fitting, described heat exchanger comprises the first air inlet, the second air inlet, the first gas outlet, the second gas outlet; Described steam-water separator import is connected with the vavuum pump exhaust outlet of combustion gas, and steam-water separator outlet is connected with air by by-passing valve on the one hand, enters valve be on the other hand connected with the first air inlet of heat exchanger by master; First gas outlet and preheating chamber and the catalyst chamber of connecting between the second air inlet of heat exchanger; The air inlet of the second gas outlet connecting fan of heat exchanger; Platinum, palladium catalyst is provided with in catalyst chamber.Described master enters valve and also installs a fresh air valve communicated with air additional with heat exchanger.Second gas outlet of described heat exchanger also installs a cold-air door communicated with air additional with the air inlet of blower fan.
Waste gas in production enters emission-control equipment under normal circumstances and processes, if when emission-control equipment meets fault, then can be met an urgent need by by-pass line emptying.When bringing into use, first fresh air valve opening, by the electric heater of preheating chamber to gas-heated, carries out preheating to catalyst.After catalyst reaches reaction temperature, equipment master enters valve opening, fresh air valve closing.Along with the catalytic reaction reaction of formation heat of waste gas, through heat exchanger when reacted Purge gas is discharged, again heat exchange is carried out to the waste gas just entered, has efficiently utilized thermal source.When the gas temperature entering blower fan exceedes temperature upper limit, cold-air flap opens the cooling of ginseng wind, protection blower fan.
The utility model starts to debug in and drops into trial run in January, 2015, has carried out environmental protection tests and checking and accepting by the end of April.Detect according to authoritative institution, waste gas row concentration mark, well below national standard, have passed the examination of environmental administration smoothly.Testing result is as shown in the table:
Through the detection of concentration of emission and the service condition feedback at several months scene, this emission-control equipment is easy and simple to handle, use reliable, effect is fine, the requirement of discharging waste gas harmless treatment when lost foam casting is poured into a mould can be met completely, illustrate that the development thinking of this product is correct, advanced technology, have promotional value to the process of waste gas in lost foam casting production from now on.
